The picture below shows a soil texture triangle. David plans to grow corn on his farm. Corn grows best in clay loam soil. Which of these is the most likely soil sample that David would select to grow corn?
Question 16 options:

sample containing 30 percent sand, 35 percent clay, and 35 percent silt

sample containing 25 percent sand, 15 percent clay, and 60 percent silt

sample containing 55 percent sand, 30 percent clay, and 15 percent silt

sample containing 40 percent sand, 15 percent clay, and 45 percent silt

im not exactly sure but i think its b!

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
